BACKGROUND OF THE INVENTION Technical Field

This disclosure relates to a display device, and more particularly to a display device capable of improving a vertical crosstalk problem.

Related Art

With the advancement of technology, flat panel displays (more particularly liquid crystal display devices) have been widely used in various fields, and thus have the superior features including the thin body, the low power consumption and the radiationless property, gradually replaced the conventional Cathode Radial Tube display devices, and applied to various electronic products, such as mobile phones, portable multimedia devices, notebook computers, liquid crystal televisions, liquid crystal screens and the like.

A liquid crystal display device mainly utilizes an electric field to control rotations of liquid crystal molecules to make light rays penetrate through the liquid crystal molecules to display an image. A pixel includes four colors of sub-pixels arranged in, for example, WRGB, and thus has the advantage of the high transmittance. At present, the liquid crystal display device has been accepted in the market, and various manufacturers have started to develop this new technology on this basis. With the continuous increases in the Pixel Per Inch and the scan frequency of the display and in order to decrease the number of the source drive ICs, there are many products each having the pixel arrangement modified from the vertical arrangement of one gate line collocating with one data line (1G1D) into half source driving (HSD) of two gate lines collocating with one data line. The HSD technology can decrease the number of the source drive ICs as well as advantageously increase the production capacity.

In addition, in order to increase the aperture ratio and the view angle, the current product tends to use the 4-domain two-pixel rendering technology, wherein the combination of two sub-pixels is utilized and different voltages are used to control different orientations of liquid crystals to render one dark and one bright (two) sub-pixels. In addition, in order to make the display frame become more uniform, the prior art also utilizes the checkerboard pattern arrangement of the 4-domain sub-pixels of the dark area and the 4-domain sub-pixels of the bright area include the design method of two different polarities (positive and negative polarities) in the overall display to decrease the flicker of the display frame. However, the main problem of this pixel design is that the same colors of sub-pixels cannot mutually offset in one frame time due to the parasitic capacitance coupling, so that the vertical crosstalk of the display frame is induced, and the frame taste is deteriorated.

In one frame time, when the gate lines are respectively and sequentially turned on by the scan signals, the data driving unit 122 may transmit the data signals corresponding to each row of sub-pixels to each sub-pixel through the data lines, so that the display panel 11 displays the image.

FIGS. 2A and 2B are schematic views respectively showing connections of pixels of the display panel with gate lines and data lines in an embodiment of this disclosure. Please refer to FIGS. 2A and 2B. FIGS. 2A and 2B show the same connection architecture. However, FIG. 2B also shows the bright and dark conditions of the sub-pixels of each pixel (the sub-pixels rendered in dashed lines are dark areas). In FIGS. 2A and 2B, 8 gate lines G1 to G8, 4 data lines D1 to D4 and 4 rows (transverse) of total 8 pixels (32 sub-pixels P) are taken as an example, but this disclosure is not restricted thereto. In different embodiment, more gate lines, data lines and pixels may be designed according to actual requirements.

In FIG. 2A, the 8 gate lines G1 to G8 may be divided into four gate line sets (surrounded by the dashed lines), wherein each set has two gate lines, that is, (G1, G2), (G3, G4) to (G7, G8), and the 4 data lines D1 to D4 are respectively represented by D1 to D4. The display panel 11 has plurality of pixels arranged in the row direction (horizontal direction) and the column direction (vertical direction). Each pixel has plurality of sub-pixels P arranged in the row direction. The plurality of sub-pixels P arranged in the row direction are respectively electrically connected to two adjacent gate lines of the corresponding row, and each of the data lines is respectively electrically connected to the two adjacent sub-pixels P of the same pixel. Specifically speaking, for example, the gate lines (G1, G2) may simultaneously drive two pixels of the first row (each pixel includes four sub-pixels P of white (W), red (R), green (G) and blue (B). The gate lines (G3, G4) may simultaneously drive two pixels of the second row, and the data lines D1, D2, D3 and D4 are respectively electrically connected to the two adjacent sub-pixels P of the same pixel. That is, each pixel is electrically connected to two data lines, respectively. Similarly, as shown in FIG. 2A, each of the data lines is connected to the two adjacent sub-pixels P of the same pixel. Therefore, the display device 1 of this embodiment adopts the half source driving (HSD) technology. In addition to reducing of the number of the source driver ICs, it is also advantageous to the improvement of the production capacity.

Each pixel of this embodiment includes four colors (WRGB) of sub-pixels P arranged in the row direction, the four colors of sub-pixels P of each pixel of the same row have the same order, and sub-pixels P in the same column have the same color. In addition, in two adjacent data lines connected to the same pixel: the n^(th) data line and the (n+1)^(th) data line are represented by D(n) and D(n+1) (n is an odd number), the colors of the sub-pixels P connected to the data line D(n) from top to bottom are sequentially WRRWRWWR, and the order is repeated; and the colors of the sub-pixels P connected to the data line D(n+1) from top to bottom are sequentially GBBGBGGB, and the order is repeated.

In addition, two adjacent pixels arranged in the column direction may form a pixel set T (surrounded by the dashed lines). Taking the pixel set in the upper left corner (labeled as T1) as an example, the sub-pixels P of the pixel in the upper half portion sequentially have a WRGB stripe arrangement, and the sub-pixels P of the pixel in the lower half portion sequentially have a WRGB arrangement. In addition, in the first pixel set, the four sub-pixels P in the upper half portion are respectively electrically connected to the same set of gate lines G1 and G2 of the corresponding row and the two adjacent data lines D1 and D2 of the corresponding column, and the four sub-pixels P in the lower half portion are respectively electrically connected to the same set of gate lines G3 and G4 of the corresponding row and the corresponding two adjacent data lines D1 and D2. The color of each pixel above takes the WRGB as an example, but it is not restricted thereto. In different embodiments, different four colors are also possible, such as RGBY, RGBC or others, and this disclosure is not restricted thereto.

The two adjacent pixels arranged in the column direction may be a first pixel set T1 and a second pixel setT 2. The first pixel set T1 and the second pixel setT 2 are sequentially connected to a first gate line, a second gate line, a third gate line and a fourth gate line. In other words, in this embodiment, as shown in FIG. 2A, the first pixel set T1 are sequentially connected to the first gate line (G1), the second gate line (G2), the third gate line (G3), and the fourth gate line (G4). The second pixel set T2 are also connected to the first gate line (G5), the second gate line (G6), the third gate line (G7) and the fourth gate Line (G8). In the first pixel set T1, the first gate line (G1) and the fourth gate line (G4) are electrically connected to the sub-pixels P in the same column, and the second gate line (G2) and the third gate line (G3) electrically connect the sub-pixels P in the same column. In the second pixel set T2, the first gate line (G5) and the fourth gate line (G8) are electrically connected to the sub-pixels P in the same column, the second gate line (G6) and the third gate line G7) are respectively electrically connected to the sub-pixels P in the same column, and the sub-pixels P respectively electrically connected to the fourth gate line (G4) of the first pixel set T1 and the first gate line (G5) of the second pixel set T2 are located in different columns, but are electrically connected with the same data line (D1) at the same time.

In the present embodiment, the first gate line (G1) of the first pixel set T1 is electrically connected to the odd-numbered sub-pixels P of the first row of pixels, the second gate lines (G2) is electrically connected to the even-numbered sub-pixels P of the first row of pixels, the third gate line (G3) is respectively electrically connected to the even-numbered sub-pixels P of the second row of pixels, and the fourth gate line (G4) is electrically connected to the odd-numbered sub-pixels P of the second row of pixels. In the second pixel setT 2, the first gate line (G5) is electrically connected to the even-numbered sub-pixels P of the third row of pixels, the second gate line (G6) is electrically connected to the odd-numbered sub-pixels of the third row of pixels, the third gate line (G7) is respectively electrically connected to the odd-numbered sub-pixels P of the fourth row of pixels, and the fourth gate line (G8) is electrically connected to the even-numbered sub-pixels P of the fourth row of pixels, and so on, but this disclosure is not restricted thereto. In a different embodiment, the first gate line (G1) of the first pixel set T1 may be electrically connected to the even-numbered sub-pixels P of the first row of pixels, and the second gate line (G2) may be electrically connected to the odd-numbered sub-pixels P of the first row of pixels (the odd and even numbers are from left to right), the third gate line (G3) may be electrically connected to the odd-numbered sub-pixel P of the second row of pixels, and the fourth gate line (G4) may be electrically connected to the even-numbered sub-pixels P of the second row of pixels. The first gate line (G5) of the second pixel set T2 may be electrically connected to the odd-numbered sub-pixels P of the third row of pixels, the second gate lines (G6) may be electrically connected to the even-numbered sub-pixels of the third row of pixels, the third gate line (G7) may be electrically connected to the even-numbered sub-pixels P of the fourth row of pixels, and the fourth gate line (G8) may be electrically connected to the odd-numbered sub-pixels P of the fourth row of pixels.

In addition, each pixel may include a first sub-pixel P, a second sub-pixel P, a third sub-pixel P, and a fourth sub-pixel P arranged in order. The first sub-pixel P and the second sub-pixel P in each pixel are electrically connected to a corresponding one of the n^(th) data line and the (n+1)^(th) data line. The third sub-pixel P and the fourth sub-pixel P are electrically connected to the other corresponding one of the n^(th) data line and the (n+1)^(th) data line (the first to fourth ones are also counted from left to right). In this embodiment, taking the data lines D1(D3) and D2(D4) as an example, the data line D1(D3) is electrically connected to the first sub-pixel P and the second sub-pixel P of each pixel in the vertical direction, and the data line D2(D4) is electrically connected to the third sub-pixel P and the fourth sub-pixel P of each pixel in the vertical direction, and so on.

Referring to FIGS. 2A and 2B in conjunction with FIG. 3, wherein FIG. 3 is a schematic view showing waveforms of the data signal corresponding to the gate line in one frame time in the connection architecture of the sub-pixel with the gate line and the data line of FIG. 2B. In a driving method of the display device of this embodiment, under the above-mentioned connection architecture, the data signal is transmitted through the plurality of data lines by the driving circuit 12 to drive the plurality of pixels of the display panel 11, wherein in one frame time, the data signal drives the two adjacent sub-pixels P of the same pixel through the n^(th) data line or the (n+1)^(th) data line using opposite polarities, the data signal drives the same pixel through the n^(th) data line and the (n+1)^(th) data line using opposite polarities (i.e., at the same time, if the n^(th) data line has the positive polarity, then the (n+1)^(th) data line has the negative polarity; or vice versa), and the data signal drives the two adjacent sub-pixels P in the column-direction through the n^(th) data line and the (n+1)^(th) data line using the same polarities.

In this embodiment, as shown in FIG. 2A, the data signal drives the two adjacent sub-pixels P of the same pixel through the n^(th) data line and the (n+1)^(th) data line that respectively includes two polarities (the positive polarity and the negative polarity), and in one frame time, polarity orders of the sub-pixels P driven by the data signal through the n^(th) data line in the column direction are negative, positive, positive, negative, negative, positive, positive, and negative. In one frame time, polarity orders of the sub-pixels P driven by the data signal through the (n+1)^(th) data line in the column direction are positive, negative, negative, positive, positive, negative, negative, and positive. In addition, in the same frame time, the polarity orders of the sub-pixels P driven through the n^(th) data line and the (n+1)^(th) data line in the column direction are respectively repeated. That is, the polarity orders of the sub-pixels P driven through the n^(th) data line in the column direction are repeatedly negative, positive, positive, negative, negative, positive, positive, and negative, and the polarity orders of the sub-pixels P driven through the (n+1)^(th) data line in the column direction repeat positive, negative, negative, positive, positive, negative, negative, and positive. Thus, in one frame time, polarities of the two adjacent sub-pixels P of the same pixel driven by the data signal through the n^(th) data line and the (n+1)^(th) data line are opposite; polarities of the same pixel driven by the data signal through the n^(th) data line and the (n+1)^(th) data line are opposite; and polarities of the two adjacent sub-pixels P of the same pixel in the column direction driven by the data signal through the n^(th) data line and the (n+1)^(th) data line are the same polarities.

Therefore, the data signal driving the sub-pixels P with the plurality of colors of each pixel includes two kinds of voltage polarities. In addition, the two adjacent sub-pixels P of the same pixel connected to the n^(th) data line and the (n+1)^(th) data have the same polarity. The data signal drives the two adjacent sub-pixels P of the first pixel set T1 and the second pixel set T2 through the n^(th) data line or the (n+1)^(th) data line using opposite polarities.

In addition, in a next frame time, the driving polarity of the data signal employs the polarity inversion driving mode, so that the properties of liquid crystal molecules are not destroyed. In other words, in this embodiment, in a next frame time, polarity orders of the sub-pixel P in the column direction driven by the data signal through the n^(th) data line and the (n+1)^(th) data line are respectively: positive, negative, negative, positive, positive, negative, negative and positive; and negative, positive, positive, negative, negative, positive, positive and negative; and in the next frame time, polarity orders of the sub-pixels P in the column direction driven by the data signal through the n^(th) data line and the (n+1)^(th) data line are respectively repeatedly positive, negative, negative, positive, positive, negative, negative and positive; and negative, positive, positive, negative, negative, positive, positive and negative.

With the connection architecture and the driving method of the gate line, the data line and the sub-pixel P, as shown in FIG. 2B, the drive circuit 12 can make the first pixel set T1 have the following properties within one frame time: the voltage polarities rendered by the four colors of sub-pixels P of the two pixels are respectively negative, positive, positive and negative (−++−); and the voltage polarities rendered by the plurality of colors of sub-pixels P of the two pixels in the second pixel set are respectively positive, negative, negative and positive (+−−+); or vice versa. That is, the voltage polarities rendered by the plurality of colors of sub-pixels P of the two pixels in the first pixel set T1 are respectively positive, negative, negative, positive (+−−+), and the voltage polarities rendered by the plurality of colors of sub-pixels P of the two pixels in the second pixel set T2 are respectively negative, positive, positive and negative (−++−). In addition, the plurality of sub-pixels P of each pixel of the same row render the same voltage polarity order, and two adjacent sub-pixels P of the same pixel set arranged in the column direction render the same voltage polarities. However, in different pixel sets, two adjacent sub-pixels P in the column direction render the opposite voltage polarities. In the next frame time, the rendered voltage polarity for all sub-pixels P is opposite to that of the previous frame time.

In addition, in one frame time, the drive circuit 12 also makes one pixel of two column-adjacent pixels become a bright area, and makes the other one pixel of the two column-adjacent pixels become a dark area. As shown in FIG. 2B, in this embodiment, one pixel of the two column-adjacent pixels becomes a bright area, and the other one pixel of the two column-adjacent pixels becomes a dark area. Also, in each pixel set T, one pixel becomes a dark area, and another pixel becomes a bright area. That is, the display panel of this embodiment adopts four colors of sub-pixels and collocates with the two pixel rendering technology.

Therefore, as shown in FIG. 3, in the above-mentioned connection architecture, the same color of bright area sub-pixels arranged in the column direction P render a positive-to-negative polarity ratio of 1:1. For example, for the data line D1, the number of positive polarity and the number of negative polarity of the red (R) sub-pixel P are equal to 1; and the number of positive polarities and the number of negative polarities of the white (W) sub-pixel P are equal to 1. Again, for the data line D2, the number of positive polarity and the number of negative polarity of the blue (B) sub-pixel P are equal to 1; and the number of positive polarities and the number of negative polarities of the green (G) sub-pixel P are equal to 1. The number of positive and negative polarities corresponding to other data lines D3 and D4 can refer to FIG. 3, and detailed descriptions thereof will be omitted.

As mentioned hereinabove, in the display device of this embodiment, a new pixel driving configuration is proposed.
